EYEGIJASS-MOUNT'ING.

Application filed August 18, 1915.

To all whom it may concern:

Be it known that 1, JOHN RU'rsoN VAN TASSEL, a citizen of the UnitedStates, and resident of Geneva, in the county of On tario and State ofNew York, have invented certain new and useful Improvements inEyeglasslVlountings, of which the following is a specification.

This invention relates to eyeglass-m0untings of the type in which thenose-guards are mounted upon levers which are pivotally connected with arigid bridge and are controlled bymeans of springs.

The object of the invention is to produce an eyeglass-mounting, of thetype in ques tion, having a simple and convenient construction by whichthe nose-guard levers are pivoted, and by which these levers and thesprings which control them are secured in place, wit-h provision fortheir easy removal and without the use of the screws usually employedfor this purpose.

The invention consists in the eyeglassmounting hereinafter described, asit is defined in the succeeding claims.

In the accompanying drawings :Figures 1 and 2 are, respectively, aplan-view and a rear-elevation of a portion of an eyeglassmountingembodying the present invention, this portion including the partsadjacent one end of the bridge; and Fig. 3 is a rear-elevation of amodified form of the invent-ion.

The eyeglass-mounting illustrated in the drawings comprises the usuallens-clips 1, lens-straps 2, bridge 3 and nose-clamp lever 1. The pivotfor the nose-clamp lever is in the form of a pin or stud 5. This studhas a portion, of reduced diameter, which is driven into a verticalperforation at the end of the bridge, and is upset or headed on itslower end to secure it firmly in place. The

nose-guard lever 1 is pivoted loosely upon this stud, and rests againstthe upper flat surface of the bridge.

The spring by which the nose-guard lever is controlled comprises acoiled portion 8 which is loosely mounted upon the stud 5. One end 8 ofthe spring extends rearwardly and is bent, at its extremity, so as tohook around the outer edge of the nose-guard Specification of LettersPatent.

lever. The other end 8 of the spring is formed as a. hook, and thishooked extremity engages one end of a pin 6 which is driven into atransverse perforation at the upper end of the stud 5. The pin 6 notonly fixes the spring against rotation on the stud, by engagement withthe hooked end 8*, but it also serves to retain the spring upon thestud, and the spring, in turn, presses the nose-guard lever firmlyagainst the upper surface of the bridge. \Vhen it is necessary to removethe spring or the nose-guard lever the pin 6 may be readily withdrawn,and the spring and the nose-guard lever may then be raised freely fromthe stud. This construction is extremely simple and inexpensive, and itavoids the objectionable tendency of the ordinary pivot-screws to workloose. An alternative form of construction is shown in Fig. 3. In thiscase the pin 6, instead of being driven into a perforation in the stud,rests in a slot at the upper end thereof, and the upper end of the studis also threaded to receive a cap-nut 9 by which the pin and the otherparts are secured in place.

I claim 1. An eyeglass-mounting having, in combination, a bridge, meansfor securing the lenses to the bridge, a stud fixed to the bridge ateach end thereof and having a. transverse opening, a nose-clamp leverlooselypivoted on each stud, a. spring having a coiled portion which isloosely mounted on each stud and extends to and engages thecorresponding nose'clamp lever, so as to retain the lever against itsbearing on the bridge, said coiled portion being of suflicient diameterto pass freely over the end of the stud, and means, for removablysecuring the spring and the nose-clamp lever in place, comprising across-pin seated in said transverse opening in the stud and engaged bythe other 'end of the spring.

2. .An eyeglass-mounting having, in combination, a bridge, means forsecuring the lenses to the bridge, a stud fixed to the bridge at eachend thereof and having a slot extending inwardly from its free end, anose-clamp lever loosely pivoted on eachl over the end of the stud, andmeans, forremovably securing the spring and the noseclamp lever inplace, comprising a crosspin seated in said slot and a nut threaded 10upon the end of the studand securing said pin in place in said slot.
